Crystal Growth and Kinetic Behaviour of Pseudoalteromonas espejiana Assisted Biosynthesized Gold Nanoparticles

Figure 6

FE-SEM images depicts growth behaviour of AuNPs at varying time intervals: 0-2 h (a), 2-12 h (b), 12-24 (c), and 24-48 h (d). Owing to phenomenon of nuclei fusion and crystal growth, a successive increase in the size of AuNPs was observed as the time increased. The scale of 100 nm is present at left bottom corner of each of the four images.
